An electronic balance which displays a correct weight value by averaging the digitized weight data outputted at predetermined time intervals from a weight detector provided in the balance. The weight data averaging to give a correct value is carried out with the number of the basis data for averaging increased each time a new weight data is obtained, after the weight data, which are largely fluctuating in the beginning, have been considered to be stabilized by being settled down in a predetermined limit. In case the once stabilized weight data are brought back into a fluctuating state owing to any external disturbance, such fluctuation is detected and the again unstabilized weight data are excluded from the averaging to give a correct weight value.

Electronic balance with averaging feature for vibration error correction

There is disclosed an electronic counting scale provided with means for calculating a maximum addable number of items to be added to an already counted known number of items with an error being eliminated from the counted number of a total items including the added items, said means calculating the maximum addable number on the basis of the standard variation of an average weight estimated from the samples taken from the entire population of the items to be counted.
